In recent projects we have been more involved in proposing raingardens and bioswales. A future resilient approach to treat rain water by allowing it to slowly seep into the ground rather then causing flash flooding and overburden on public surface water drainage systems. These swales and raingardens will also contribute to the cities biodiversity and regulate temperatures.
Image 1 and 2 are of a great reference project – Mortsel Fort 4 by OKRA Landschapsarchitecten, Image 3 is a bioswale in Bushwick, Brooklyn.
